qudiscretize {QUBIC} | R Documentation |
qudiscretize
delivers a discrete matrix. It is useful if we just want to get a discretized matrix.
qudiscretize(x, r = 1L, q = 0.06)
x |
the input data matrix, which could be the normalized gene expression matrix or its qualitative representation from Qdiscretization or other discretization ways.
(for example: a qualitative representation of gene expression data) |
r |
Affect the granularity of the biclusters. The range of possible ranks.
A user can start with a small value of |
q |
Affect the granularity of the biclusters. The percentage of the regulating conditions for each gene.
The choice of |
qudiscretize
convert a given gene expression matrix to a discrete matrix.
It's implimented in C++, providing a increase in speed over the C equivalent.
